GEORGE WV. BENTON, OF SOMERS, ASSIGNOR TO FREDERICK N. DU BOIS,

' OF NEW YORK, N. Y.

SELF-CLOSING FAUCET.

SPECIFICATION forming part of Letters Patent No. 444,018, dated. January 6, 1891. Application filed August 27, 1889. Serial No. 322,159. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. RENTON, of Somers,.in the county of Westchester and State of New York, have invented new and useful Improvements in Self- Closing Faucets, of which the following is a specification.

My invention has relation to that class of faucets in which the valve is closed upon its seat by spring-pressure; and the objects of my improvement are to diminish friction and to increase the spring-pressure, which makes it more durable.

In the annexed drawings, making a part of this specification, Figure l is a longitudinal central section of the faucet. Fig. 2 is a longitudinal section of the valve and adjuster. Fig. 3 is an elevation of the same, and Fig. 4 is a view of the adjuster.

A is the body of the faucet, constructed with a long chamber B above the valve-seat O and containing a valve D, which is tubular in form, but with a head in the lower end, to which is attached the usual washer, which closes on the valve-seat. This valve may be used with the Benton ejector-faucet passing through a bridge in the water-chamber, or it may be packed between the valve and the wall of the chamber B in a well-known manner. In the latter case the wall of chamber B would be made to form a packingchamber. drical valve is made to fit neatly in the hole through the bridge at O, and again at some point, say B, where the wall of the chamber B is contracted to bring it into close contact with the valve.

\Vithin the valve D is a strong spiral spring E of such length that in closing the valve it will only be contracted about one-sixth of. the distance itis capable of being contracted. By this means, although the power of the spring is considerable, it will close the valve, not too suddenly, but with a movement which will insure a soft cushion-like action and at the same time preserve the durability of the spring, never taxed to more than a small fraction of its power.

At the top of the hollow valve and above In the case illustrated the cylinthe spring is the adjuster Ga cup-formed piece within the valve and formed with four slots at a distance of ninety degrees from one another. The spring presses this adjuster against the cap F, which is screwed down upon the outside of B. By turning the cap more or less upon its thread it will force the adjuster to a corresponding degree against the spring and so regulate the tension thereof.

A journal-pin I, surrounded by a frictionsleeve, is secured near the upper end of the valve D, and passes through opposite slots in the adjuster G, so that the valve D may have free vertical play.

A handle K passes through a slot (formed at M) in the chamber B and through a corresponding slot in the adjuster and extends under the pin I. It is fulcrumed at L on the lower edge of the slot, resting in a notch in the lever, and serves, when the long arm is forced down, to lift the valve in a right line and without strain on its bearings, because the force is applied by the short arm of the lever bearing freely against the centrallyplaced pin. The lever has sufficient free play to permit all the movement of the parts necessary for the proper regulation of the spring-tension.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In combination with the body A B, provided with internal separated guides or bearings O B, avalve D, fitting therein, a spring E, serving to hold the valve to its seat, a pin I, carried by thevalve, and a lever K, mounted in the body of the faucet and engaging the pin I, all substantially as shown and described.

2. In a faucet, the combination, with the main body and its sliding valve D, of a spring, a follower bearing upon the spring, a cap fitting upon the body of the faucet and serving to adjust the follower, and means for raising the valve, all substantially as shown.

3. In a faucet, the combination, with the main body, of the hollow valve mounted therein, a spring contained within the valve,

an adjnstnble mp1, and a follower inter- I In testimony whereof I have hereunto set posed between the spring andcap,:1ll suhmy hand in the presence of two attesting 1o stantially as shown. r l Witnesses.

I. In a faucet, the combination, with the GEORGE V BENTON 5 main body, of' the hollow valve D, provided l with a pin I and with a spring E, a slotted In presence offollower G, a lever K, and an adjustable cap, i FRANK DU 1301s, all combined substantially as shown. 1 FRANK G. DU BOIS.
